2007 CHRYSLER PACIFICA immobilizer

Automatic Transaxle Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK. It also prevents shifting out of
PARK unless the key is in the ACC, or ON positions, and
the brake pedal is depressed.
SENTRY KEY — IF EQUIPPED
The Sentry Key Immobilizer System prevents unautho-
rized vehicle operation by disabling the engine. The
system does not need to be armed or activated. Operation
is automatic, regardless of whether the vehicle is locked
or unlocked.
The system uses ignition keys, which have an embedded
electronic chip (transponder), to prevent unauthorized
vehicle operation. Therefore, only keys that are pro-
grammed to the vehicle can be used to start and operate
the vehicle. The system will shut the engine off in two (2)
seconds if someone uses an invalid key to start the
engine.NOTE:A key, which has not been programmed, is also
considered an invalid key even if it is cut to fit the
ignition lock cylinder for that vehicle.
During normal operation, after turning on the ignition
switch, the Vehicle Security Alarm Indicator Light will
turn on for three (3) seconds for a bulb check. If the light
remains on after the bulb check, it indicates that there is
a problem with the electronics. In addition, if the light
begins to flash after the bulb check, it indicates that
someone used an invalid key to start the engine. Either of
these conditions will result in the engine being shut off
after two (2) seconds.
If the Vehicle Security Alarm Indicator Light turns on
during normal vehicle operation (vehicle running for
longer than 10 seconds), it indicates that there is a fault in
the electronics. Should this occur, have the vehicle ser-
viced as soon as possible.

Shaft Lock Module (Vehicles Equipped with
Premium Security System) — If Equipped
The shaft lock module is located inside the steering
column. The module works in conjunction with the
Sentry Key to prevent the steering shaft from rotating if
someone inserts an invalid ignition key into the ignition
lock cylinder in the instrument panel.
NOTE:
•The Sentry Key Immobilizer System is not compatible
with remote starting systems. Use of these systems
may result in vehicle starting problems and loss of
security protection.
•Exxon/Mobil Speed Pass,™ additional Sentry Keys, or
any other transponder equipped components on the
same keychain will not cause a key-related (transpon-
der) fault unless the additional part is physically held
against the ignition key being used when starting thevehicle. Cell phones, pagers, or other RF electronics
will not cause interference with this system.
All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE:Only keys that have been programmed to the
vehicle electronics can be used to start the vehicle. Once
a Sentry Key has been programmed to a vehicle, it can
not be programmed to any other vehicle.
At the time of purchase, the original owner is provided
with a four digit PIN number. This number is required
for dealer replacement of keys. Duplication of keys may
be performed at an authorized dealer or by using the
Customer Key Programming procedure. This procedure
consists of programming a blank key to the vehicle
electronics. A blank key is one which has never been
programmed and needs to be cut.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE: When having the Sentry Key Immobilizer
System serviced, bring all vehicle keys with you to the
dealer.
Customer Key Programming
You can program new sentry keys to the system if you
have two valid sentry keys by performing the following
procedure:
1. Cut the additional Sentry Key Transponder blank(s) to
match the ignition switch lock cylinder key code.
2. Insert the first valid key into the ignition switch and
turn the ignition switch ON for at least 3 seconds but no
longer than 15 seconds. Turn the ignition switch OFF and
remove the first key.
3. Insert the second valid key and turn the ignition
switch ON within 15 seconds. After ten seconds a chime
will sound and the Theft Alarm Light will begin to flash.
Turn the ignition switch OFF and remove the second key.4. Insert a blank Sentry Key into the ignition switch and
turn the ignition switch ON within 60 seconds. After 10
seconds a single chime will sound. The Theft Alarm Light
will stop flashing, turn on for 3 seconds; then turn off.
The new Sentry Key has been programmed.The Keyless
Entry Transmitter will also be programmed during this
procedure.Repeat this procedure to program up to a
total of 8 keys. If you do not have a programmed sentry
key, contact your dealer for details.
NOTE:If a programmed key is lost, see your dealer to
have all remaining keys erased from the systems
memory. This will prevent the lost key from starting your
vehicle. The remaining keys must then be repro-
grammed. All vehicle keys must be taken to the dealer at
the time of service to be reprogrammed.
